After King Saul's death, David was proclaimed king of
Judah at Hebron, and after the murder of Saul's son Ishbosheth, David was
crowned king by the tribes of Israel.

David conquered Jerusalem from the Jebusites and made it his capital and center of worship. He expanded his
kingdom by victories over the Philistines, Moabites, Ammonites, and
Edomites, and suppressed many rebellions.

2 Samuel
8:11-15 "Which also king David did dedicate unto the LORD, with
the silver and gold that he had dedicated of all nations which he
subdued; Of Syria, and of Moab, and of the children of Ammon, and of
the Philistines, and of Amalek, and of the spoil of Hadadezer, son
of Rehob, king of Zobah. And David gat [him] a name when he returned
from smiting of the Syrians in the valley of salt, [being] eighteen
thousand [men]. And he put garrisons in Edom; throughout all Edom
put he garrisons, and all they of Edom became David's servants. And
the LORD preserved David whithersoever he went. And David reigned
over all Israel; and David executed judgment and justice unto all
his people."

2 Samuel
5:7-10 "Nevertheless David took the strong hold of Zion: the
same [is] the city of David. And David said on that day, Whosoever
getteth up to the gutter, and smiteth the Jebusites, and the lame
and the blind, [that are] hated of David's soul, [he shall be chief
and captain]. Wherefore they said, The blind and the lame shall not
come into the house. So David dwelt in the fort, and called it the
city of David. And David built round about from Millo and inward.
And David went on, and grew great, and the LORD God of hosts [was]
with him."

David
in Smith's Bible

David3. David's reign.--
1. As king of Judah at Hebron, 7 1/2 years. 2Sa 2:1 ... 5:5
Here David was first formally anointed king. 2Sa 2:4 To Judah his
dominion was nominally confined. Gradually his power increased, and
during the two years which followed the elevation of Ish-bosheth a
series of skirmishes took place between the two kingdoms. Then
rapidly followed the successive murders of Abner and of Ish-bosheth.
2Sa 3:30; 4:5 The throne, so long waiting for him, was now vacant,
and the united voice of the whole people at once called him to
occupy it. For the third time David was anointed king, and a
festival of three days celebrated the joyful event. 1Ch 12:39 One of
David's first acts after becoming king was to secure Jerusalem,
which he seized from the Jebusites and fixed the royal residence
there. Fortifications were added by the king and by Joab, and it was
known by the special name of the "city of David." 2Sa 5:9; 1Ch 11:7
The ark was now removed from its obscurity at Kirjath-jearim with
marked solemnity, and conveyed to Jerusalem. The erection of the new
capital at Jerusalem introduces us to a new era in David's life and
in the history of the monarchy. He became a king on the scale of the
great Oriental sovereigns of Egypt and Persia, with a regular
administration and organization of court and camp; and he also
founded an imperial dominion which for the first time realize the
prophetic description of the bounds of the chosen people. Ge
15:18-21 During the succeeding ten years the nations bordering on
his kingdom caused David more or less trouble, but during this time
he reduced to a state of permanent subjection the Philistines on the
west, 2Sa 8:1 the Moabites on the east, 2Sa 8:2 by the exploits of
Benaiah, 2Sa 23:20 the Syrians on the northeast as far as the
Euphrates, 2Sa 8:3 the Edomites, 2Sa 8:14 on the south; and finally
the Ammonites, who had broken their ancient alliance, and made one
grand resistance to the advance of his empire. Full Article

David
2. Conquests Abroad:
King of all the Israelite tribes, David found his hands free to
expel the foreigners who had invaded the sacred territory. His first
step was to move his headquarters from the Southern Hebron, which he
had been compelled at first to make his capital, to the more central
Jerusalem. The fort here, which was still held by the aboriginal
Jebusites, was stormed by Joab, David's nephew, who also
superintended the rebuilding for David. He was in consequence
appointed commander-in-chief (1 Ch 11:6,8), a post which he held as
long as David lived. The materials and the skilled workmen for the
erection of the palace were supplied by Hiram of Tyre (2 Sam 5:11).
David now turned his attention to the surrounding tribes and
peoples. The most formidable enemy, the Philistines, were worsted in
several campaigns, and their power crippled (2 Sam 5:17 ff; 8:1). In
one of these David so nearly came by his death, that his people
would not afterward permit him to take part in the fighting (2 Sam
21:16,17). One of the first countries against which David turned his
arms was the land of Moab, which he treated with a severity which
would suggest that the Moabite king had ill-treated David's father
and mother, who had taken refuge with him (2 Sam 8:2). Yet his
conduct toward the sons of Ammon was even more cruel (2 Sam 12:31),
and for less cause (10:1 ff). The king of Zobah (Chalkis) was
defeated (2 Sam 8:3), and Israelite garrisons were placed in Syria
of Damascus (2 Sam 8:6) and Edom (2 Sam 8:14). The sons of Ammon
formed a league with the Syrian kingdoms to the North and East of
Palestine (2 Sam 10:6,16), but these also had no success. All these
people became tributary to the kingdom of Israel under David (2 Sam
10:18,19) except the sons of Ammon who were practically exterminated
for the time being (2 Sam 12:31). Thus, Israel became one of the
"great powers" of the world during the reign of David and his
immediate successor. Full Article
